Contactless reader IC
Write data:
To write data to the CLRC663 using the UART interface the following structure has to be
used.
Remark: Note: The Trigger on IF3 pin has to be set, otherwise no “write data” is possible
The first send byte defines both, the mode itself and the address.
10.4 I2C-bus Interface
An Inter IC (I2C) bus interface is supported to enable a low cost, low pin count serial bus
interface to the host. The implemented I2C interface is implemented according the NXP
Semiconductors I2C interface specification, rev. 3.0, June 2007. The implemented
